, fhis invention Irelatesto linotype machines and more particularly, to those ,partsthereof whose duty it isv to assemble. the matrices as I the samearedelivered under the control of 5 the keyboards o fthe ma'chines. I ,A machine of the type-to ,wh'ch reference is made includes. an n assembler, entrance which comprises a number of verti cal ways down .whichthe matrices slideas they are selective face ,ofa downwardly Imoving matrix deliv ery belt, so that the rateof matrix movement to the assemblerfproper Econtrolledby the speed of the belt The matrices lie flat on the belt and'i therefore atfan angle with the vertical, and in the assembling process these matrlces must be arranged in parallel abut-3 ting relation, verticallypositioned. Further, the matrices: must be so'assembled in the or- 'der of depression, of thefcorresponding; keys of the keyboard. The' nmatricesfr'each the belt ordinarily in their proper order but theymaybe very closely space'd thereon, and par I fticularly where thi'sis the case;as the matrices run'oif the belt there isja malfunctioning of the machine in that two matrices are assem r bled in"transp0sedrelation, the one which should: follow, bein' ahead of theother.

A It is, an object-o my inventionytherefore, to provide means for eliminating such transposition. A

The exact nature of invention to ether 7 with further objectsadvantages thereof will be apparentfrom' the followingdescrip- I ti'on'taken in connection withtheaccompany= ing drawings in which Fig.1 is an assembly view more orless diagrammatic, showing pertinent parts of a linoty'pe machine 'with' my invent-ion incorporatedtlierein FigL 2 is an 1540' end view of my transposition eliminator appearing inFig, 1 and Fig. Biis a} detail section as in Fig. 1.

, With referencenowto thejdrawings, '1 is a lower and driving] pulley of the matrix delivery belt 2. 3-is theyassembler star wheel.

a eeee 'auythe,'dpmaon of these parts is follows: Matrices aredeliv'ered to the upper oli stretch of Q the; belt '2 under the control of the j U keyboardof the machine. The matrix is r, thus shown lying fiat upon thebelt andmoW ingdownwardly therewith,to the lettlFig. "1 1" matrix is slidth'e'refromonto anddown alon the'railfe until its lower endstrikes one '0' f the lobes of the star wheel 3, the matrix then beingin the position as indicated at B. The

T e bracket 7 has a horlzontal le 12 adapted to stand out from the space band chute 8 as indicated, Fig. 1, when the bracket is so secured on the machine. This leg 12 of the bracket carries a bolt such as the thumb screw 13, between the head of which and the arm may be secured an end 14 of the strap 15. A member 16, preferably resilient but less limber than the strap, is provided as backing means therefor, having an end also secured under the head of the thumb screw and itsopposite end extending downwardly as at 17. The free or lower extremity 18 of the strap member 15 extends below that of the backing member 16 and the free extremities of both these members lie generally alongside the rail 4. The portion of the backing member underlying the thrumb screw 13 is slotted as at 19 to clearthe bolt or screw portion 20 of the thumb screw whereby the position of the depending portion 17 of the backing member may be adjusted to vary its clearance from the chute 4. The corresponding secured end of the strap 15 may be similarl slotted or may simply have an opening through which the member 20 passes. In either event,.adjustment of the backingmember efiects corresponding adjustment of the free end 18 of the strap, and such adjustment is made dependent upon matrix thickness as willbe understood by one familiar with the art. The adjustment is preferabl such that the largest matrix of the font to e handled will have contact at least with the end 18 of a the strap as it slides down the chute 4. i

Thus when'proper adjustment is made the free end of the strap forms a sort of flap member having frictional properties and engageable byeach matrix in succession as the matrices move along the rail to enter the asseming effect is had upon the space bands, saving the usual wear and tear particularly upon 7 thespace band lugs. v

"I have found inpracticethat transposition is made practically impossible by the proper employment of my device as described.

While Iam not prepared to exactly analyze the reasons for such accomplishment it may well be that the'matrices have a slight wedging effect between the free ends of the de- Vhat I claim is:

1. In a linotype machine having a matrix assembler and a matrix rail leading thereto, means for eliminating transposition of matrices at the entrance to the assembler and comprisin a non-metallic flap member of yieldable ut non-resilient material and a metallic backing member for supporting said flap member with its free end overhanging the backing member and alongside the rail, to be engaged by each matrix in succession as the matrices move along the rail to enter the assembler. A

2. In a linotype' machine having a matrix assembler and a matrix rail leading thereto, means for eliminating transposition of matrices at the entrance to the assembler and comprising a flap member of yieldable but nonresilient material and a backing member for supporting said flap member, and means associated with said members for securing one of the ends of each in independentlyadjusted relation, to position the opposite and free ends thereof alongside the rail, with that of the flap member overhangin that of the backing member to be'engage by each matrix in succession as the matrices move along the rail to enter the assembler.

In testimony whereof I hereby aflix my signature.

scribed eliminator parts and the chute, or at 8 least occupy so much of the clearance therebetweenas tomake it impossible for a matrix succeeding on the belt to overrun a precedin 0 matrix betweenthese parts. a
